Electrode Process
The foundation of battery quality. This stage determines over 70% of the final product's energy density and performance.
πΒ Mixing : Blending active materials, binders, and additives into a homogeneous slurry.
π‘οΈ Coating : Applying slurry onto metal foils (Al, Cu) at high speed.
π₯ Drying : Evaporating solvents via thermal or IR systems.
π Pressing : Compressing the electrodes to increase energy density and bonding strength.
βοΈ Slitting : Precision cutting to specific cell dimensions.
Transforming processed electrodes into the final cell shape. Precision logistics and environment control are critical here to prevent contamination.
ποΈ Notching : Creating tabs on the uncoated areas of the electrodes for current collection.
π Stacking : Precisely layering the anode, separator, and cathode in a sandwich structure.
π¦ Packing : Inserting the stacked core into a aluminum can or pouch case for protection.
π Electrolyte Injection : Injecting the ionic fluid followed by the final vacuum sealing of the cell.
"Breathing life" into the battery. This is where the cell becomes an active energy storage device through the initial charge cycles.
ποΈ Formation : Initial charging to create the Solid Electrolyte Interphase (SEI) layer.
β Aging : Storing cells at specific temperatures to ensure electrochemical stability.
π€ Degassing : Removing gases generated during the formation process.
π¬ Grading : Conducting final OCV/IR testing to categorize cell quality.
